Biological / Autrack
- Name
- Autrack
- Taxonomic Class
- Chozo Autonomous Machine / Extensible-Neck Defense Droid
- Homeworld
- SR388
- Known Range
- Chozo settlement corridors, cavern defenses, old SR388 structures, protected doorways, and cover-rich patrol routes
- Power Source
- Ancient power cell, corridor-defense programming, sensor input, and residual Chozo maintenance architecture
- Threat Response
- Cover-based plasma fire, extensible-neck targeting, programmed intruder response, central CPU failure, and patrol persistence after abandonment
- Origin / Deployment
- Chozo manufacture during SR388 settlement; left behind after evacuation, with many units deteriorated and others still following original defense routines
- Physiological Summary
- The Autrack is a Chozo-built SR388 defense droid designed for corridors and caverns. Its extensible neck allows the main body to remain behind rock or wall cover while the plasma cannon rises above the barrier, fires, and retracts before return fire can reliably destroy the central chassis.
Overview
The Autrack is an autonomous Chozo defense construct believed to originate from the period of Chozo settlement on SR388. It was built for practical work: guarding corridors, protecting important structures, and using the local terrain as part of its defensive logic.
Old source material describes many Chozo automatons left behind after evacuation. Some failed, some continued their original programming, and others remained active without meaningful purpose. The Autrack belongs to the dangerous middle category: still capable, still obedient to old routines, and no longer supervised by its builders.
The construct is filed in the Biological archive because abandoned machines can become part of a living hazard environment. An Autrack shapes how organisms move through old settlements, which routes remain dangerous, and how ancient Chozo sites continue defending themselves long after cultural withdrawal.
Anatomy And Physiology
The main chassis houses locomotion, power, targeting systems, and the central processing unit. Its outer shell is not exceptionally durable against sustained energy or kinetic attack, so the unit compensates by exposing as little of itself as possible. The body is designed to survive by using terrain rather than by absorbing every hit.
The extensible neck is the defining structure. It carries the plasma cannon above low walls, rock shelves, or corridor barriers while the central body remains protected. The movement is brief and purposeful: rise, aim, discharge, retract, and reassess.
The plasma cannon is powerful and long-ranged for a corridor defense droid. Damage to the neck reduces firing reliability, while severe damage to the central CPU can produce total failure. DSI files should treat the neck, cannon, shell, and CPU as a single defensive anatomy.
Habitat And Range
Autracks are most effective in cover-rich corridors and caverns. A typical position places the chassis behind a wall, rock, or structural lip with enough clearance for the cannon neck to rise. Open rooms reduce the advantage of the design, while cluttered ruin passages make it unusually dangerous.
Habitat evidence includes worn recesses behind low barriers, scorch lines over cover edges, repeated neck-extension scratches, power-cell residue, and old Chozo service points. These traces can reveal an Autrack position even if the unit is dormant or destroyed.
The range is tied to Chozo settlement architecture on SR388. Patrol routes may persist around abandoned living spaces, work sites, doors, and protected buildings. The unit may classify modern lifeforms as intruders simply because its old authorization map no longer matches the current ecology.
Behavior And Ecology
The Autrack does not hunt, feed, or patrol from curiosity. It evaluates routes, identifies perceived intruders, takes cover, extends the plasma cannon, fires, and retracts. Its behavior is old command logic applied to a changed world.
The construct uses its surroundings with surprising efficiency. A rock outcrop becomes armor, a corridor bend becomes a firing lane, and a doorway becomes a protected kill zone. This ability to exploit environment is the most important feature preserved from the old source record.
Over long abandonment, Autracks can become ecological hazards. Native organisms may avoid defended corridors, scavengers may feed on bodies killed by the cannon, and explorers may misread a dormant droid as debris. The machine continues shaping movement even when its original purpose is gone.
Origin And Development
Autrack origin is Chozo manufacture rather than biological reproduction. The construct was created to make settlement life easier and safer, particularly by guarding important sites and performing defense work in environments too dangerous or tedious for constant living oversight.
After the Chozo left SR388, many automatons remained behind. Some deteriorated beyond repair, while others continued their programming for centuries. The Autrack record should therefore include corrosion, maintenance loss, power-cell condition, and whether the unit is following a coherent route or a broken loop.
A complete origin file should connect the droid to the settlement it guarded. Service bays, authorization markers, old barriers, route geometry, and damage to the central CPU all explain the machine more fully than a static scan. Its life history is the afterlife of Chozo infrastructure on SR388.
